Emma Watson was dumped by reality star Francis Boulle because he didn't want to date "some child actress". The diamond specialist, who appears in the Channel 4 show 'Made in Chelsea', claims he wanted to achieve his own level of fame and didn't want to be eclipsed by Watson's career.The pair were first spotted together at a Cartier polo party in 2008, where their relationship is understood to have begun. Speaking to the UK's heat magazine, Boulle explained, "We had a bit of a thing a while back, but I have always been an ambitious person and I want to achieve my own notoriety for what I've done". Francis admitted he is no longer in contact with Watson, who has risen to become one of the world's most recognisable actresses, but claims their paths cross from time-to-time, adding, "We do share a lot of mutual friends". 'Made in Chelsea', which premiered in May 2011, follows a wealthy set of twenty-somethings who live the high life in London's Knightsbridge, Belgravia and on the Kings Road. Boulle, an entrepreneur of American, French and Norwegian descent, is credited with pitching the idea of the show to Channel 4 producers.More recently, he set up the website 'Sexy MP', in which users can rate members of parliament on their attractiveness.
